Torenia · Accepted scientific name
Scientific literature: Very Sparse (0 studies) · ★☆☆☆☆
Torenia, often affectionately called the weeping bacopa, is a charming shade-loving plant prized for its delicate, trumpet-shaped blossoms. These vibrant flowers add a splash of color to garden borders and hanging baskets alike, thriving in moist, filtered light. A fascinating aspect of this genus is the presence of betacyanin, a pigment responsible for some of its deep, intense hues. This unique chemical compound provides a rich visual complexity that distinguishes it from many other common bedding plants. Whether grown for its lush foliage or its striking blooms, Torenia remains a favorite for creating serene, shaded landscapes.

Identification
Biological Activities
Compounds
Torenia naturally contains endogenous anthocyanins within its flower petals, which contribute to its native pigmentation. Recent genetic engineering efforts have successfully introduced new pigments into the plant to modify its flower color. Through this process, researchers confirmed that Torenia can be engineered to contain betanin, a primary betacyanin pigment. Additionally, the study found that the plant can also accumulate isobetanin to a lesser extent. This combination of native anthocyanins and newly introduced betalains allows for a significant increase in flower color variation.
